Bringing back the classics
Refurbishing ‘classic’ PAS 5500 and TWINSCAN lithography systems for a new life and a new purpose
We measure a machine’s life in decades, not years. Almost every single ASML lithography system sold is still in use at a customer fab.
The PAS 5500:
a machine with a history
Before EUV, before immersion, and even before our TWINSCAN systems, there was the PAS.
In 1991, seven years after the company was founded, we launched the PAS 5500, which turned out to be our breakthrough platform. This system was able to dramatically reduce manufacturing times for our customers, and its modular design enabled them to produce multiple generations of advanced chips using the same system.
How system refurbishment works
In our Linkou Factory, engineers in blue cleanroom suits take apart machines and clean, repair and tweak them to ensure that they perform to their original specifications.
The machine is taken apart into individual modules, which are then repaired and tested individually. They are then re-assembled and integrated into the like-new machine that meets all original specifications. We then grant a new warranty on the system. By 2018, ASML had refurbished more than 400 PAS 5500 systems.
“Tune my ride”
During the process of refurbishment, we are also able to upgrade the machine, convert it to a different model, or adapt it for a particular purpose.
The PAS 5500 is a versatile machine that can be adapted for many new markets and special applications. For example, by adding front-to-backside alignment, the system can be optimized for MEMS chips such as accelerators (the chips that can tell which way is ‘up’). The system can also be adapted for ‘through-silicon via’ (TSV) applications, radio frequency chips, thin-film heads for hard disk drives, or bowed wafer handling for LED applications. Enhancements to throughput and overlay can also reduce costs in high-volume manufacturing.
Support through 2030 and beyond
Through holistic support for our classic, or ‘mature’ technology, we ensure a long and fruitful life for ASML lithography systems. We know the value of supporting our customers on more mature technology, so we work with them to create lasting and flexible solutions.
